Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a headset is used to display a virtual scenario during vehicle movement, then the user can view a virtual scenario, but the virtual scenario is not dynamically associated with real-time changes in the vehicle's path and direction, causing mismatched observation points that lead to nausea and dizziness

Engineering Contradiction:

Improvedynamic association of virtual scenario with vehicle movementVSAvoidnausea and dizziness

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically updates the virtual scenario based on real-time vehicle movement data from sensors (accelerometers, gyroscopes, magnetometers). The observation point in the virtual environment moves synchronously with the actual vehicle, creating a dynamic adaptation that prevents motion sickness while maintaining immersive viewing

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses sensor feedback from the vehicle's inertial measurement units to continuously adjust the virtual scenario's observation point. This closed-loop feedback ensures the virtual view remains synchronized with actual vehicle motion, preventing the mismatch that causes nausea and dizziness

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the virtual scenario is fixed and not updated in real-time, then the system complexity is reduced, but the observation point does not follow the vehicle's movement, reducing immersion and realism

Engineering Contradiction:

Improveobservation point synchronizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses a multi-functional approach where a single processing unit handles both the acquisition of sensor data and the generation of virtual scenario updates. This universal processor manages multiple functions (reading sensor inputs, calculating observation point transformations, rendering virtual views) without requiring separate complex subsystems

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system is self-sufficient by using the vehicle's own motion sensors to automatically update the virtual scenario. The observation point calculation is performed autonomously based on sensor data, without requiring external control systems or complex manual configuration, thus maintaining simplicity while achieving synchronization

Inventive Principle:

Principle #25Self-service

AI summary

The present invention relates to a system (1) configured to select a portion of a virtual scenario (S1v,S2v) during the movement of a vehicle (V) within a geographical area of interest (A). Said system (1) is capable of obtaining information associated with the vehicle (V) regarding the position, the rotation with respect to the x, y, z axes of a reference system associated with the vehicle itself, as well as the heading, and applying this information to a virtual geographical area (Av) associated with said geographical area of interest (A), so that each movement of the vehicle (V) in the geographical area of interest (A) corresponds to a respective movement in the virtual geographical area (Av). In this way, the viewing of a virtual scenario (S1V, S2V) changes according to the movement of the vehicle. The present invention relates also to a vehicle (V) comprising said system, as well as to a method for selecting a portion of a virtual scenario during the movement of a vehicle (V) within a geographical area of interest (A) by means of said system.
